Definitions

  • the twine arm assembly has a twine arm with a guide section and a control section, being moveably connected to each other and moveable as a unit between a tying position and a rest position.
  • a guide member is connected to one section.
  • FIGS. 4-7 discloses in FIGS. 4-7 a twine arm assembly having two carriers each for two twine arms. Both carriers are pivoted by a motor and controlled by a linkage connected at there ends to a frame of a round baler.
  • the twine arms are moveable between a rest position close to a center area of the round baler and underneath a tongue, and a twine delivery position close to a side area of the round baler.
  • the guide member can be brought into a position or decoupled or changed or altered in any other way such that the guide section can be brought into a position, where twine can be inserted easily.
  • a position may be at the side area of the round baler, where it is easy to reach.
  • the guide section may be pivoted during insertion of the twine, to make insertion as convenient for an operator.
  • the guide member can be collapsible, foldable, telescopically adjustable, or can consist of a flexible means such as a rope, a wire, a chain or the like. It is also possible to provide for a coupling of the guide member on the control or guide section, which can be decoupled easily making the guide section freely moveable. Movement of the guide section may happen in or transverse to the twine arm movement plane during operation, i.e. horizontally or vertically.
  • the control section may consist of several components or be a single unit.
  • a simple design for connecting the two parts is a bearing, which makes both parts pivotable on each other.
  • the bearing may include the lock or not.
  • Synchronization of the movement of both twine guide sections and control sections is achieved, if both control sections are connected among each other by a linkage, such as a rod, a cable, fluid line, etc.
  • twine guide members are provided on the guide section and/or on the guide member, which have an element biased against a fixed or moveable element, between which a gap is formed to receive twine.
  • These elements can be shims, discs, plates, etc. which are under the pressure of a spring and which abut other shims, etc. or one of the sections or the guide member, a frame, etc. and form a gap, preferably in V-shape, into which a twine strand can be inserted radially, rather than through an eyelet, a hole, a tube or the like.
  • Deactivating the tensioner in the twine guide helps to feed the twine into the bale chamber, since it does not create any resistance. Such deactivation may happen manually or mechanically, if the twine guide and tensioner during its movement abuts a stop, cam, or the like; or it may be deactivated electrically.
  • FIG. 2 is a top view of the twine arm assembly in a rest position
  • FIG. 3 is a top view of the twine arm assembly in an operating position
  • FIG. 4 is a top view of the twine arm assembly in the rest position, whereas a guide member is in a service condition;
  • FIG. 5 is a side view of the twine guide means
  • FIG. 7 is the twine guide and tensioner of FIG. 6 shown in an activated position.
  • a round baler 10 has a frame 12 , a chassis 14 , a tongue 16 , a pick-up 18 , an inlet 20 to a bale chamber (not shown).
  • a twine arm assembly 22 is shown in further detail in FIGS. 2-4 .
  • the round baler 10 is of an ordinary variable chamber type, which forms cylindrical bales from crop lying on a field; such round balers 10 are widely known.
  • the pick-up 18 extends at least over the full width of the round baler 10 or even beyond of it and can be lifted and lowered during operation.
  • a baffle (not shown) is provided above the pick-up 18 and below the tongue 16 , which assists in feeding the crop taken up by the pick-up 18 into the inlet 20 .
  • the inlet 20 is located behind or downstream of the pick-up 18 and allows crop to enter into a bale chamber.
  • Twine 26 also enters the bale chamber at the inlet so as to be routed around the peripheral surface of the bale inside the bale chamber, as is widely known.
  • the twine arm assembly 22 is located underneath the cross beam 8 of the frame 12 and underneath the tongue 16 and feeds twine 26 through the inlet 20 into the bale chamber, where it is caught by a rotating bale. Further reference is made to FIGS. 2-4 .
  • the twine arm assembly 22 consists of two units 28 and 30 , each having a twine arm 32 with a control section 34 and a guide section 36 , and a guide member 38 .
  • the two units 28 , 30 are interconnected by means of a linkage 40 and are commonly operated by an actuator 42 . While in this case two units 28 and 30 are present, there could be more or less.
  • These units 28 , 30 are substantially of the same design but are arranged in a mirror image fashion.
  • the control sections 34 are formed substantially as a straight bar, rod, tube or sheet metal with reinforcements and provided with a front bearing 44 and a rear bearing 46 in the respective end region.
  • a short lever 48 is provided, having a bearing 50 being eccentric to the front bearing 44 .
  • a cantilever 52 is attached to the control section 34 of the left control section 34 and extends from latter under an angle of about 90 degrees. “Left” and “Right” are meant as seen from the perspective of a person looking into the forward drive direction of the round baler 10 .
  • a bearing 54 is provided in the free end area of the cantilever 52 .
  • Bearings 44 are connected to the frame 12 at the underside of the cross beam 8 and enable the control section 34 to pivot horizontally with respect to the frame 12 approximately 135 degrees between a position transverse to the driving direction of the round baler 10 and about 45 degrees inclined to it.
  • the guide section 36 is formed of sheet metal with reinforcement elements and has a twine tube 56 , a twine guide and tensioner 58 , a bearing 60 and the bearing 46 .
  • the twine tube 56 is located at the end opposite the bearing 46 . While the bearing 46 connects the guide section 36 to the control section 34 , the twine tube 56 is located at the free end of the guide section 36 and extends beyond that, although this is not really necessary.
  • the twine 26 runs to the twine tube 56 and is brought to the surface of the bale.
  • the bearing 60 is located between the twine tube 56 and the bearing 46 and the twine guide and tensioner 58 is located quite close to it.
  • the twine guide and tensioner 58 comprises two shims 62 of a frustrum shape arranged about an axis 64 and pressed onto each other by means of a spring 66 , retained and tensioned by a nut 68 . Due to the frustrum shape of the shims 62 a V-shaped gap is provided, into which the twine 26 is inserted.
  • One of the reinforcements is formed as a catcher 106 with a cavity, which is suitable to receive bearing 88 , as will be described later.
  • the guide member 38 comprises two parts 70 , 72 , which are pivotably connected to each other by means of a bearing 74 , and a lock 76 .
  • Part 70 is pivotably received with one end on a bearing 78 fastened to the frame 12 , whereas the bearing 74 is provided at the opposite end.
  • Another twine guide and tensioner 58 is arranged on the bearing 78 .
  • the other part 72 is pivotably received with one end area on bearing 74 and with the other end area on bearing 60 .
  • the twine arm 32 , the guide member 38 and the part of the frame 12 between the bearing 44 and 78 form a triangle with substantially similar length of its edges.
  • the lock 76 is provided laterally of the bearing 74 and is able to allow or prevent a pivoting movement of the parts 70 , 72 relative to each other.
  • shim 62 is received on the pin 92 to form a gap between the shim 62 and the housing 100 , into which the twine 26 can enter.
  • the shim 62 is kept in place by a cotter pin 102 and discs 104 .
  • Activator 98 is fastened either to the frame 12 , to the cross beam 8 or e.g. to an extended portion of part 72 .
  • the linkage 40 is formed as a rod being connected at each end to the bearing 50 on the control sections 34 , whereas the bearings 50 and thus the linkage 40 are arranged opposite of a plane through bearings 44 to provide for a mirror image like movement of both units 28 , 30 . While the linkage 40 shown is of a fixed length, it could also be adjustable in length.
  • the arrangement of the bearing 88 and of the beam 82 and its lever arm 86 is such, that the right hand control section 36 touches the beam 82 , when it moves towards the rest position as shown in FIG. 2 , by means of a cam 92 and a bearing 91 or similar.
  • the extensions of control sections 34 and 36 perpendicular to the plane of movement are designed such, that said bearing 91 may pass the arm 34 , but not the arm 36 with the cam 92 .
  • the tying operation starts from the situation shown in FIG. 2 , whereas the two parts 70 , 72 of the guide member 38 are locked, i.e. they form a substantially straight element.
  • the actuator 42 When the actuator 42 is extended, it will swing cantilever 52 about the bearing 44 and with it control section 34 of the left unit 30 . Due to the connection via linkage 40 the control section 34 of the right unit 28 is pivoted. Since the guide sections 36 of both units 28 , 30 are connected via guide member 38 to the frame 12 , the movement of the guide section 36 is controlled, such that it assumes the position shown in FIG. 3 close to the side of the round baler 10 . In this position the twine tube 56 gets closest to the bale and brings the twine 26 in connection with it for getting wound about it.
  • the twine arms 32 When the actuator 42 is retracted again, the twine arms 32 will again move towards their rest position shown in FIG. 2 , whereas the right control section 34 moves the beam 82 with its knife 84 through the abutment of bearing 88 in the catcher 106 towards the strands of the twine 26 , which accumulate in the center of the round baler 10 .
  • the knife 84 hits the twine 26 and pushes it against the frame 12 , the strands are separated.
  • the spring 90 helps to bring the beam 82 out of the way of the twine arms 32 , once the tying operation starts.
  • the lock 76 is released and the two parts 70 , 72 can collapse, such that the guide section 36 assumes the position shown in FIG. 4 at the side of the round baler 10 and possibly even beyond its lateral edge, where the access is free.
  • the twine 26 is inserted into the twine tube 56 it is pulled radially into the twine guide and tensioner 58 , where it is tensioned and guided.
  • the parts 70 , 72 are brought back into their normal position and locked.
